Abstract

The present invention provides an ankle joint prosthesis assembly, comprising: a base body, the base body includes a main body and a connection part arranged on the main body; an adjustment structure, the adjustment structure is adjustable and arranged on the connection part to change the upper end of the adjustment structure The distance between the substrate and the pad structure, which is arranged on the main body and outside the connecting portion. The technical solution of the present application effectively solves the problem in the related art that the tibial side prosthesis cannot achieve short-term and long-term fixation with the distal tibia under different bone defects of the distal tibia.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ankle joint prosthesis assembly. Background technique [0002] The talus, the distal end of the tibia, and the lower end of the fibula together form the ankle joint, which is divided into three parts: the head, the neck, and the body. It is the joint with the largest load in the human body. Ischemia of the body of the talus, cartilage damage, fractures, and tumors can all cause ankle joint lesions, causing difficulty in walking and even disability. [0003] In related technologies, ankle joint resurfacing is one of the main diagnostic and therapeutic methods for reconstructing the structure and function of the ankle joint. However, after the tibial side of the ankle joint is affected, especially when there is a bone defect on the tibial side, the short-term and long-term fixation of the tibial side prosthesis to the distal tibia cannot be achieved. Moreover, it i...
